Development scripts

We maintain a script/ folder that contains some useful script to ease testing on Garage.

A fully integrated script, test-smoke.sh, runs some basic tests on various tools such as minio client, awscli and rclone. To run it, enter a nix-shell (or install all required tools) and simply run:

nix-build # or cargo build
./script/test-smoke.sh

If something fails, you can find useful logs in /tmp/garage.log. You can inspect the generated configuration and local data created by inspecting your /tmp directory: the script creates files and folder prefixed with the name "garage".

Bootstrapping a test cluster

Under the hood test-smoke.sh uses multiple helpers scripts you can also run in case you want to manually test Garage. In this section, we introduce 3 scripts to quickly bootstrap a full test cluster with 3 instances.

1. Start each daemon

./script/dev-cluster.sh

This script spawns 3 Garage instances with 3 configuration files. You can inspect the detailed configuration, including ports, by inspecting /tmp/config.1 (change 1 by the instance number you want).

This script also spawns a simple HTTPS reverse proxy through socat for the S3 endpoint that listens on port 4443. Some libraries might require a TLS endpoint to work, refer to our issue #64 for more detailed information on this subject.

This script covers the Launching the garage server section of our Quick start page.

2. Make them join the cluster

./script/dev-configure.sh

This script will configure each instance by assigning them a zone (dc1) and a weight (1).

This script covers the Configuring your Garage node section of our Quick start page.

3. Create a key and a bucket

./script/dev-bucket.sh

This script will create a bucket named eprouvette with a key having read and write rights on this bucket. The key is stored in a filed named /tmp/garage.s3 and can be used by the following tools to pre-configure them.

This script covers the Creating buckets and keys section of our Quick start page.

Handlers for generic tools

We provide wrappers for some CLI tools that configure themselves for your development cluster. They are meant to save you some configuration time as to use them, you are only required to source the right file.

awscli

source ./script/dev-env-aws.sh

# some examples
aws s3 ls s3://eprouvette
aws s3 cp /proc/cpuinfo s3://eprouvette/cpuinfo.txt

minio-client

source ./script/dev-env-mc.sh

# some examples
mc ls garage/
mc cp /proc/cpuinfo garage/eprouvette/cpuinfo.txt

rclone

source ./script/dev-env-rclone.sh

# some examples
rclone lsd garage:
rclone copy /proc/cpuinfo garage:eprouvette/cpuinfo.txt

s3cmd

source ./script/dev-env-s3cmd.sh

# some examples
s3cmd ls
s3cmd put /proc/cpuinfo s3://eprouvette/cpuinfo.txt

duck

Warning! Duck is not yet provided by nix-shell.

source ./script/dev-env-duck.sh

# some examples
duck --list garage:/
duck --upload garage:/eprouvette/ /proc/cpuinfo
